I have very long (below the bra band), straight, fine and colored Chinese hair. Curls often don't stay that long for me or they almost fall out completely. My goal with the remington was to make a light stroke at the ends of my hair. I went for a beachy/romantic look, so to speak. I used this in the travel curl set from Carmen that I only applied to the ends of my hair, but I had the idea that I had too little control over the curl, it also made my hair a bit frizzy. With this curling iron I hoped to have a little more control over the direction and firmness of the curl.
With this curling iron I managed to get (on a first try!) a nice curl in the ends of my hair that lasted until the next day! It is true that prior to use I have used a product (a curl facilitating hairspray from Japan) that probably contributed to this + a lot of hairspray after curling. My second attempt went a little less well, the coarse curl was almost gone after 4 hours (and immediately looked less good than the first time), but there was still a slight stroke in the points. I think this time I grabbed too big strands of hair (didn't have that much time left), which made the curl too limp. So a tip is not to take too large sections of hair to curl, maybe 5-6 strands per side (I had 4 per side this time), depending on how much hair you have (I have fine hair, but medium amount of hair ).
The pliers warmed up quickly (within a minute) and I did not find it difficult to use. I did use the gloves that come with it, but even without it I did well, no burns :).
You have different heat settings, but I would take the time to figure out which setting works best for you. Start at one of the lowest settings, if the curl doesn't stay in it properly, just do a higher setting next time; you really don't want to damage your hair unnecessarily, because if it's good you will really get addicted to these tongs :). I don't have much experience with curling irons myself, but I'm very satisfied with them! Would really use products if you have fine hair like me, that not only extends the life of your curl but also ensures that the curl is more beautiful :).
